 - Seasonal charm work in flight:
   - source-backed holiday, New Year's, Halloween, spring, and gift prompts are now part of Build B
   - `RN_` holiday greeting files are now bucketed as greetings so seasonal replies stay visible in the catalog
+  - birthday celebration lines are now bucketed separately, and birthday memory writes a loop-scoped holiday record so personal dates can join the holiday list later
 - Presence and thought follow-ups in flight:
   - `welcome back`, `what are you thinking`, `what have you been doing`, and `what did you do` are now part of Build B

 - port holiday-aware personality responses as a visible extension of the new persona slice
 - start with a small, source-backed set (for example birthdays/holidays already represented in legacy data paths)
 - ensure holiday responses feel characterful while still routing through stock-compatible payloads
+- imported Build B holiday buckets now include holiday, holiday greeting, holiday gift, and birthday celebration lines
 - use a loop-scoped merged holiday list in the cloud protocol so system holidays and custom person holidays can coexist
 - source system holidays from a live holiday provider and keep `IsEnabled = false` records available for holiday suppression
 - keep birthday/custom holiday authoring aligned with person memory so future proactivity can suppress or promote holidays per loop
+- birthday memory writes now create loop-scoped holiday records, which keeps the holiday list extensible without changing the protocol shape again
